Too Many Endurance Athletes Are Racing on Too Few Carbs, Study Finds
A 2025 study found non-elite endurance athletes consume roughly 20 percent fewer carbohydrates on race day than planned, with marathoners averaging just 22 grams per hour against guidelines of 60 to 90.
Sawe's marathon fuel: what hydrogel gels actually do
Sabastian Sawe broke two hours at the 2026 London Marathon in 97-gram Adidas shoes. But the Maurten hydrogel gels pinned to his bib may have mattered more. A new RCT finds they do not make you faster, but they do make you steadier.
What Runners Get Wrong About Race-Day Fueling
Most runners under-fuel, mistime their intake, or ignore carbohydrate type on race day. Research on 250-plus London Marathon runners and studies on pre-race timing and multiple transportable carbohydrates show how much performance is left on the table when fueling goes wrong.
Will you ever BQ? Data, age and what the science says
About 13 percent of US marathon finishers run a Boston qualifying time, and a 6:51 cutoff in 2025 made the published standard a polite suggestion. Two peer-reviewed papers on masters endurance athletes explain why the qualifying ladder is partly generous and largely about training volume.
